The movie is scheduled to be released on November 21 this year in Japan and will feature the main cast of the series.
So far, the movie will feature a new song from Megumi Nakajima (Ranka Lee). Most likely there will be one from May’n as well.
Whether or not if the movie a straight up continuation of the story, or a retelling like DYRL, I haven’t seen any details yet. At least, this will tide me over until the Gundam 00 Movie next year.

For the ill-infomed, Macross Frontierwas a recent installment/spin-off of the original anime.
As with much of the Macross franchise, expect hell to freeze over before a US release of the movie or the Macross Frontier TV series proper, so get ready for those torrents.

EDIT: Itsuwari no Utahime is a compilation movie with some new footage. Another story from ANN confirms that a second Macross Frontier movie is in development, this one with an all new story. There are no further details at the moment.
